A coding scheme for the two-receivers Gaussian broadcast channel (BC) with feedback is proposed. For some asymmetric settings it achieves new rate pairs. Moreover, it achieves prelog 2 when the noises at the two receivers are fully positively correlated an ...

Sampling of Sparse Channels with Common Support

Martin Vetterli, Ali Hormati, Yann Barbotin

The present paper proposes and studies an algorithm to estimate chan- nels with a sparse common support (SCS). It is a generalization of the classical sampling of signals with Finite Rate of Innovation (FRI) and thus called SCS-FRI. It is applicable to OFD ...

Robust IEEE 802.15.4a Energy Detection Receiver Using Statistical Interference Modeling

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection is appealing for IEEE 802.15.4a receivers as it allows to exploit the ranging capabilities and the multipath resistance of impulse-radio UWB at a reasonable complexity. IEEE 802.15.4a receivers operate with interference created by uncontro ...

Consider a K-user interference channel with time-varying fading. At any particular time, each receiver will see a signal from most transmitters. The standard approach to such a scenario results in each transmitter-receiver pair achieving a rate proportiona ...

Non-coherent energy-detection receivers are an attractive choice for IEEE 802.15.4a networks. They can exploit the ranging capabilities and the multipath resistance of impulse-radio ultra-wide band (IR-UWB) at a low complexity. However, IEEE 802.15.4a rece ...

An Energy Detection Receiver Robust to Multi-User Interference for IEEE 802.15.4a Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection receivers are appealing to IEEE 802.15.4a low data-rate networks because of their low complexity. With a reasonable energy consumption, these receivers can exploit the ranging capabilities and multipath resistance of impulse-radio UWB (IR- ...
